Agenda Transforming Wireless World • Next Generation Wireless Requirements • Spectrum Access Service • SAS Notional Architecture • Inference, decision making and enforcement • Model City Program for Testing and Measurement • Model City framework • Current Status • 2
Transforming Wireless World… IMPLICATIONS IMPERATIVES Spectrum sharing is a must • Lack of spectrum for new siloed • New paradigm, policies and spectrum • allocations rules Ever increasing applications and • Need new technologies, usage • spectrum demand measurements/inferences/models, Need to optimize usage efficiencies, • enforcement policies and implementation new spectrum R&D New dimensions to security threats • 3
Motivation to Measurements Interference Analysis and Network Based Assessment Measurements Incumbent Incentives, Protection Business Models Device Based/ Crowd Measurements Sourcing Modelling, Security, Data Immersive Certification Sharing Measurement Analytics Enforcement Effective Dynamic Measurements are key to next generation Spectrum Sharing-based networking 4

Model City Under Consideration Key Events and possible contributors Spectrum Bands In Gaps to Address Sharing Discussions Technology Presidential Memorandum Interference 2010 NTIA 1675-1710 MHz Receiver CAC Characteristics 1755-1850 MHz PCAST Realistic Security July 2012 3550-3650 MHz Urban Spectrum Testing: NITRD/ Access Service 5350-5470 MHz Model City WSRD 5850-5925 MHz Monitoring & Enforcement Others… Presidential FCC New Modelling Memorandum Experimental 2013 Licensing Program Model City Test and Measurements can contribute Significantly to advancing spectrum Innovation & National Rule Making 7
Model City: Key Areas of Discussion Testing Governance Collaboration • Multi-stakeholder • Cities for testing • Enabling testing advisory • Type of innovations collaboration • Criteria to identify to be supported • Funding plan by cities for testing • Spectral bands for collaborating entities • Process for test testing • CRADA/ Other infrastructure and • Technologies, tools, agreement vehices coordination applications, use for coordination with • Test licensing cases government agencies • Establishing • Test plan and as needed processes execution • Incentives for Model • Building • Potential role of City testing collaboration Govt./Industry • Outreach • Information interference availability and coordination access • Data analytics There are several steps to the formation of the Model Cities; However, multiple cities and collaborators are already showing interest 8
